Description

Network searching method and network searching device, and terminal

Specification network search method and web search device, field of terminal technology

The present invention relates to wireless communication technology field, in particular to a kind of network search method, a kind of web search device and a kind of terminal.Background technology

The communications field enters the 4G epoch, whole network framework has very big change compared with 2G/3G, and voice service is used as the most basic and most important demand of wireless telecommunications, how to be realized in 4G, no small trouble is brought to Virtual network operator and terminal business, major chip manufacturers and 3GPP tissues propose different solutions and selected for operator at this stage, mainly include single-card double-standby scheme (SGLTE/SVLTE), circuit domain dropping scheme（CSFB (Simultaneous Voice and LTE, LTE is synchronous with voice network to be supported by), S VCC/VOLTE, wherein SVLTE）Single-card double-standby scheme has no special requirements to network, and network side is changed small, it is not necessary to disposes IMS, enjoys Domestic Carriers to favor.

At this stage in 4G networking initial stage, the 4G network coverages do not reach seamless coverage also, or even operator takes Regional covering in some cities and area due to cost considerations, and this certainly exists 4G off-grid problems for mobile terminal.

As shown in Fig. 1,4 Jia surely in fig. l (a) in, UE is treated or is singly treated 4G networks 3G and 4G networks are double；When UE leaves 4G network's coverage areas, 4G network off-grids can be caused, so as to enter the situation shown in Fig. 1 (b), it is connected to 2G and 3G network, or when UE leaves 4G and 3G network's coverage areas, possibly into the situation shown in Fig. 1 (c), that is, it is only connected to 2G networks, or UE is likely to be at or into the region for not having any mobile network covering shown in Fig. 1 (e), UE off-grids（OOS, out of service)；And when UE is come back under 4G networks, as shown in Fig. 1 (d), user is it is clearly desirable that 4G networks can be returned quickly, but for the consideration to power consumption of terminal, it is clear that can not cause UE-directly ceaselessly attempt the search to 4G networks and access operation. Therefore, how to avoid UE electricity caused by blindly searching net from wasting, enable to UE to access particular network as early as possible again（Such as 4G networks）, as technical problem urgently to be resolved hurrily at present.

The content of the invention

The present invention is based on above mentioned problem, propose a kind of new technical scheme, can be according to the change in location situation of terminal, can either control terminal web search frequency and/or number of times, avoiding frequently blindly searching net causes the waste of power consumption of terminal, terminal can be helped to access particular network as early as possible again, help to lift Consumer's Experience.

In view of this, the present invention proposes a kind of network search method, including：Terminal is from first network off-grid or has not yet registered to the first network；When detecting the presence of data traffic requirement, the terminal performs the search operation to the first network.

In the technical scheme, presence situation based on the data traffic requirement in terminal, determine whether to perform the search operation to first network, it is all based on demand so that searching net every time and initiates, both the use demand and applied mental of user had been met, blindness can be avoided to search net again causes the power consumption of terminal to increase, and helps to extend the stand-by time of terminal.

Therefore, it whether there is data traffic requirement in terminal by detecting so that avoid blindly searching net when in the absence of data traffic requirement, and the search operation to first network can be started in time when there is data traffic requirement.

Wherein,, can be by residing in the second network, to ensure the continuity of communication after terminal is from first network off-grid for multimode terminal.Or, the technical scheme of the application is also applied for other scenes, such as terminal do not cover started shooting in the region of first network when, the second network can be registered to first, and combine the above-mentioned search operation based on data traffic requirement, while ensuring terminal fast search to first network, it is to avoid blindly search net, help to reduce power consumption of terminal.

First network and the second network can be the different mobile radio networks of any two, such as, for the base station under same position, the coverage of first network is likely less than the coverage of the second network.More specifically and preferably, such as first network can be 4G networks（Such as LTE), and the second network can be 2G networks（Such as GSM, GPRS, EDGE CDMA IX etc.）Or 3G network（Such as CDMA2000, TD-SCDMA/TD-HSPA, WCDMA/HSPA）.

2G/3G networks because layout time is early, the network optimization is perfect, its usual network coverage than the large and complete face of 4G networks that was laid out later, therefore 4G off-grids and 2G/3G not off-grid situation at certain A little regions easily occur.

In the above-mentioned technical solutions, it is preferable that in the case where detecting the presence of the data traffic requirement, in addition to：When the terminal resides at the second network, if the terminal corresponding serving cell and/or adjacent cell in second network change, the terminal performs the search operation to the first network.

In the technical scheme, when residing in the second network, because terminal is necessarily connected to neighbouring cell, so that by knowing that the situation of change of terminal corresponding serving cell and/or adjacent cell in the second network, it just can directly reflect change in location situation of the terminal under the second network, that is the change of serving cell and/or adjacent cell, necessarily due to the change in location of terminal caused by, and the change in location of relatively large distance most probably occurs for terminal.

Therefore, when the change in location that terminal is produced is more than or equal to predetermined value, terminal is highly likely to enter/reentered the overlay area of first network, then now by performing the search operation to first network, both added and searched net success rate, blindness can be avoided to search net again causes the power consumption of terminal to increase, and helps to extend the stand-by time of terminal.

In the above-mentioned technical solutions, it is preferable that judge that the corresponding serving cell of the terminal and/or adjacent cell change and specifically included：The terminal changes in the mark of the corresponding serving cell of second network and/or adjacent cell, the terminal performs cell selection or cell reselection operation, the terminal and perform cell handover operations or the terminal in second network in second network and performs cell update operation from the second network off-grid, the terminal in second network.

In the above-mentioned technical solutions, it is preferable that also include：When the continuous frequency of failure of the search operation of first network described in the terminal-pair is more than or equal to preset times, the terminal stops performing the search operation to the first network of the situation of change based on the serving cell and/or adjacent cell.

In the technical scheme, pass through the statistics to the continuous frequency of failure so that when the continuous frequency of failure is more（The such as continuous frequency of failure is more than or equal to preset times）When, show not cover first network interior in a big way.Thus in follow-up operation, even if the corresponding serving cell of terminal and/or adjacent cell change, the search operation to first network will not be also performed accordingly, contributes to terminal to reduce power consumption, extend the stand-by time of terminal.

In the above-mentioned technical solutions, it is preferable that in the case where detecting the presence of the data traffic requirement, in addition to：Obtain the real-time position information of the terminal；When true according to the real-time position information When the change in location distance of the fixed terminal is more than or equal to default variable quantity, the terminal performs the search operation to the first network.

In the technical scheme, when residing in the second network, by the real-time position information for obtaining terminal, it becomes possible to the accurate change in location situation for understanding terminal, and when terminal there occurs the change in location of relatively large distance, start the search operation to first network in time.

In the above-mentioned technical solutions, it is preferable that the real-time position information for obtaining the terminal is specifically included：By the satellite positioning module in the terminal, the real-time position information is obtained；And/or when the terminal resides at the second network, the real-time position information of the terminal is received from network side.

In the technical scheme, for the real-time position information of terminal, the satellite positioning module direct measurement that can be configured by terminal itself, specifically can be using the GPS alignment systems in such as U.S., the BEI-DOU position system of China, the GALILEO positioning system in Europe, Russian GLONASS alignment systems；The real-time position information of terminal can also be known by network side and the terminal is informed, specifically, the real-time position information of the terminal can be determined by the base station under the second network according to the receiving side signal parallactic angle from the terminal or the relation of the signal receiving strength according to the terminal respectively between multiple base stations etc..

In the above-mentioned technical solutions, it is preferable that also include：When the continuous frequency of failure of the search operation of first network described in the terminal-pair is more than or equal to preset times, the terminal stops performing the search operation to the first network based on the change in location distance.

In the above-mentioned technical solutions, it is preferable that when the search operation of first network described in the terminal-pair the continuous frequency of failure be more than or equal to preset times when, in addition to：Start timer, and the end The search operation to the first network is initiated after the timer expiry in end.

In the technical scheme, using the web search mode based on timer, i.e. per after when the timer times out, terminal performs the search operation to first network, if success, accesses first network, otherwise resets timer, to wait after the timer again time out, the search operation to first network is re-executed.

Cell is based on because when the continuous frequency of failure is more, terminal stops performing（Serving cell and/or adjacent cell）What is changed searches net operation, thus operated by the above-mentioned web search based on timer, so that while power consumption of terminal is reduced, the promptness scanned for first network can be ensured to a certain extent, it is to avoid the overlay area of user's entrance/return first network can not but be registered for a long time.

In the above-mentioned technical solutions, it is preferable that also include：If the search operation to the first network that the terminal is initiated after the timer expiry fails, the continuous frequency of failure is then subtracted into default value, to re-execute the situation of change based on the serving cell and/or adjacent cell or the search operation to the first network based on the change in location distance by the terminal.

In the technical scheme, when based on timer search net operation failure when, for searching the relatively low situation of net frequency based on timer, in order to improve the promptness that terminal accesses first network again, change " the continuous frequency of failure " can be passed through, such as the continuous frequency of failure is reduced to less than preset times, net operation is once searched based on cell change/change in location distance so as to make terminal to re-execute, the overlong time of timer expiry is avoided waiting for, helps to shorten the stand-by period of user.

In the above-mentioned technical solutions, it is preferable that also include：When the search operation to the first network that the terminal is initiated after the timer expiry fails, the timer is restarted immediately, or increase the timing time of the timer according to predetermined manner and restart the timer.

In the technical scheme, by the timing time for increasing timer, frequency of the terminal execution to the search operation of first network can further be reduced, so as to contribute to the power consumption for reducing terminal, be conducive to saving power for terminal, when quickly being moved particularly with the region on a large scale without the LTE network coverages, searching times can be significantly reduced.It is of course also possible to use fixed timing length, without being adjusted to timing.

In the above-mentioned technical solutions, it is preferable that when the search operation of first network described in the terminal-pair the continuous frequency of failure be more than or equal to preset times when, in addition to：If the terminal initiates routing region updating request or the band of position updates request, the search operation to the first network is initiated. In the technical scheme, due to the initiation that routing region updating is asked or band of position renewal is asked, it is necessarily accompanied with the change in location of terminal, and terminal probably due to the change of the band of position and come back to the overlay area of first network, thus the search operation of first network is not blindly performed accordingly, but first network may be successfully searched with larger, contribute to user's success, rapidly recover to first network, lift Consumer's Experience.

In the above-mentioned technical solutions, it is preferable that also include：If the search operation to the first network for updating request based on routing region updating request or the band of position that the terminal is initiated fails, the continuous frequency of failure is then subtracted into default value, to re-execute the situation of change based on the serving cell and/or adjacent cell or the search operation to the first network based on the change in location distance by the terminal.

In the technical scheme, if being asked based on routing region updating or the band of position updating the net operation of searching asked and still failed, then in order to improve the promptness that terminal accesses first network again, change " the continuous frequency of failure " can be passed through, such as the continuous frequency of failure is reduced to less than preset times, net operation is once searched based on cell change/change in location distance so as to make terminal to re-execute, the overlong time that terminal initiates routing region updating request or band of position renewal request is avoided waiting for, helps to shorten the stand-by period of user.

In any of the above-described technical scheme, it is preferable that also include：In the case where there is data traffic requirement in the terminal, when judging whether the changing value of one or more selected parameters of the terminal under second network is more than or equal to default changing value accordingly, it is allowed to which the terminal performs the search operation to the first network；Wherein, the selected parameter includes at least one of or its combination：Signal intensity, the transmission power intensity of the terminal and/or the transmission signal intensity of the corresponding serving cell of the terminal and/or adjacent cell, the corresponding emission delay of the terminal and/or reception delay, the corresponding bit error rate of the terminal and/or Block Error Rate, the corresponding signal to noise ratio of the terminal and/or signal interference ratio.

It is when the change in location of relatively large distance occurs for terminal, the changing value for causing above-mentioned various selected parameters is larger in the technical scheme（Such as larger than or equal to corresponding default changing value）, and terminal is likely to the overlay area of therefore entrance/return first network.So, pass through the determination of the changing value to above-mentioned selected parameter, the change in location situation of terminal can be reflected, this is determined whether that terminal performs the search operation to first network, it can avoid blindly searching net to a certain extent, help to reduce the power consumption of terminal, be conducive to saving power for terminal.

In order to be more clearly understood that the above objects, features and advantages of the present invention, the present invention is further described in detail with reference to the accompanying drawings and detailed description.It should be noted that in the case where not conflicting, the feature in embodiments herein and embodiment can be mutually combined.

Many details are elaborated in the following description to fully understand the present invention; but; the present invention can also be different from other modes described here to implement using other, and therefore, protection scope of the present invention is not limited by following public specific embodiment.

Fig. 2 shows the schematic flow sheet of network search method according to an embodiment of the invention.As shown in Fig. 2 network search method according to an embodiment of the invention, including：Step 202, terminal is from first network off-grid or has not yet registered to the first network；Step 204, when detecting the presence of data traffic requirement, the terminal performs the search operation to the first network.

First network and the second network can be the different mobile radio networks of any two, such as, for the base station under same position, the coverage of first network is likely less than the coverage of the second network.More specifically and preferably, such as first network can be 4G networks（Such as LTE), and the second network can be 2G networks（Such as GSM, GPRS, EDGE CDMA IX etc.）Or 3G network（Such as CDMA2000, TD-SCDMA/TD-HSPA, WCDMA/HSPA etc.）. First, and cell change combination

When judging whether to need to initiate the search operation to first network by terminal, cell change situation can be combined with the data traffic requirement in terminal.Wherein, Fig. 3 shows combination cell change according to an embodiment of the invention to realize the schematic flow sheet of web search.

As shown in figure 3, combination cell change according to an embodiment of the invention realizes that the flow of web search includes：

Step 302, detect and there is data traffic requirement in terminal；

Step 304, when corresponding serving cell and/or adjacent cell change the terminal in second network, the terminal performs the search operation to the first network.

1st, Rule of judgment

In flow as shown in Figure 3, step 304 relate to the judgement for " the corresponding serving cell of terminal and/or adjacent cell change ".Specifically, the deterministic process can use various ways, for example, can use following Rule of judgment：

The mark of the corresponding serving cell of terminal and/or adjacent cell changes, terminal performs reselection operation, terminal from the second network off-grid, terminal and performs cell handover operations or terminal execution cell update operation.

Therefore, when meeting at least one of above-mentioned condition, you can judge that the corresponding serving cell of terminal and/or adjacent cell are changed.

2nd, idiographic flow

Below with cell ID（That is the mark of serving cell and/or adjacent cell）Change condition be Example, above-mentioned technical proposal is described in detail with reference to Fig. 4.Wherein, Fig. 4 performs web search for embodiment illustrated in fig. 3 based on cell change（Specially step 304) schematic flow sheet.

As shown in figure 4, in the case of it is determined that there is data traffic requirement in terminal, the flow according to an embodiment of the invention for performing web search based on cell change includes：

Step 402, UE (user equipment, i.e. terminal）From LTE off-grids or have not yet registered to LTE networks, and enter LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions.

Specifically, here by LTE be " first network ", 2G/3G networks be " the second network " exemplified by illustrate.

Step 404, after UE is registered to 2G/3G networks, the cell ID of serving cells and/or adjacent cell of the record UE under 2G/3G networks.

Specifically, cell ID (i.e. Cell ID) can be the cell ID of wireless network in the narrow sense;Can also be sensu lato cell ID, such as CGI (Cell Global Identifier, Cell Global Identification）.

Step 406, judge whether the cell ID of serving cell and/or adjacent cell changes.

Specifically, on the one hand, the cell ID for the precedence record that is stored with UE;On the other hand, when performing or will perform cell change there is the cell ID of Target cell in UE.Therefore, by the way that the cell ID of the cell recorded ID and Target cell is compared, you can determine whether cell ID changes, so as to judge whether the corresponding serving cells of UE and/or adjacent cell change.

Wherein, if changing, into step 408, otherwise continue waiting for.

Step 408, based in step 406, for the judged result of cell ID situation of change, a LTE search registration is performed.

Specifically, because cell ID change means that UE there occurs the change in location of relatively large distance, then UE is likely to re-move to LTE coverages, thus with " cell ID changes " for condition, perform the search to LTE and register operation, it can either avoid blindly searching terminal power loss caused by net, the success rate that UE accesses LTE network again can be improved again.

Step 410, judge whether LTE search registration operations succeed, if success, into step 412, otherwise return to step 404.

Step 412, UE exits LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions, into normal operating conditions.Certainly, only illustrated herein by taking " off-grid " scene as an example.In fact, the technology of the present invention Scheme is also applied for other scenes.Such as when UE do not cover started shooting in the region of LTE network when, can be by being first registered to 2G/3G networks, it is then based on the flow as shown in Fig. 4, realize the search to LTE networks, so as to can either fast search LTE networks, it can avoid blindly searching net again, help to reduce UE power consumption.

Step 502, detect and there is data traffic requirement in terminal；

Step 504, the real-time position information of the terminal is obtained；

Step 506, when the change in location distance that the terminal is determined according to the real-time position information is more than or equal to default variable quantity, the terminal performs the search operation to the first network.

In the technical scheme, by the real-time position information for obtaining terminal, it becomes possible to the accurate change in location situation for understanding terminal, and when terminal there occurs the change in location of relatively large distance, start the search operation to first network in time.

1st, acquisition of information

In flow as shown in Figure 5, step 504 relate to the acquisition for " real-time position information ".Specifically, the acquisition process can use various ways, for example can be in the following way：(1) terminal is obtained

(2) network side is obtained

Preferably, the real-time position information for obtaining the terminal is specifically included：For multimode terminal, if terminal resides in the second network, the real-time position information of the terminal can be received from the network side of the second network by terminal.

Specifically, i.e., the real-time position information of terminal is obtained by network side, and the real-time position information is informed into terminal.Network side can obtain the real-time position information of terminal by following manner：

1) after endpoint registration to the second network, by some base station, corresponding cell provides service.The base station can determine the real-time position information of terminal when receiving the signal for carrying out self terminal according to the reception azimuth of the signal.

2), can be in the same time after endpoint registration to the second network（Or the period）The relation of the signal receiving strength between terminal and multiple base stations is determined respectively, so that it is determined that the real-time position information of the terminal.

2nd, idiographic flow

Above-mentioned technical proposal is described in detail with reference to Fig. 6.Wherein, Fig. 6 performs web search for embodiment illustrated in fig. 5 based on change in location distance（Specially step 504 and step 506) schematic flow sheet.

As shown in fig. 6, in the case of it is determined that there is data traffic requirement in terminal, the flow according to an embodiment of the invention for performing web search based on change in location distance includes：

Step 602, UE is from LTE off-grids or has not yet registered to LTE networks, and enters LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions.

Step 604, UE real-time position information is recorded.

Specifically, the real-time position information can be measured by UE itself, UE is informed after can also being measured by network side.

Step 606, according to UE real-time position information, judge whether UE change in location is met more than or not less than default distance change amount L0 apart from L.If meeting, into step 608, otherwise continue waiting for. Specifically, on the one hand, the real-time position information for the precedence record that is stored with UE；On the other hand, UE also constantly obtains new real-time position information.Therefore, by the way that the front and rear real-time position information recorded successively is compared, you can determine UE change in location distance.

Step 608, based in step 606, for the judged result of UE change in location situation, a LTE search registration is performed.

Specifically, due to UE change in location it is in larger distance when, make it be likely to re-move to LTE coverages, thus can either avoid blindly search net caused by terminal power loss, the success rate that UE accesses LTE network again can be improved again.

Step 610, judge whether LTE search registration operations succeed, if success, into step 612, otherwise return to step 604.

Step 612, UE exits LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions, into normal operating conditions.Certainly, only illustrated herein by taking " off-grid " scene as an example.In fact, technical scheme is also applied for other scenes.Such as when UE do not cover started shooting in the region of LTE network when, can be by being first registered to 2G/3G networks, it is then based on the flow as shown in Fig. 6, realize the search to LTE networks, so as to can either fast search LTE networks, it can avoid blindly searching net again, help to reduce UE power consumption.

3rd, terminal power saving

Preferably, in technical scheme as shown in Figure 3 or Figure 4, the continuous frequency of failure of the LTE search operations based on cell change can be counted, i.e., the continuous frequency of failure.When the continuous frequency of failure is more（The such as continuous frequency of failure is more than or equal to preset times）When, show not cover first network interior in a big way.And, in technical scheme as shown in Figure 5 or Figure 6, the continuous frequency of failure of the LTE search operations based on change in location distance can be counted, i.e., the continuous frequency of failure.When the continuous frequency of failure is more（The such as continuous frequency of failure is more than or equal to preset times）When, show not cover first network interior in a big way.Thus in follow-up operation, following processing modes can be used：

When the continuous frequency of failure of the search operation of first network described in the terminal-pair is more than or equal to preset times, the terminal stops performing the search operation to the first network based on cell change/change in location distance, contribute to terminal to reduce power consumption, extend the stand-by time of terminal.

4th, cell change/change in location distance is combined with other technologies means Hereinbefore, described by Fig. 3 and Fig. 4 with reference on the basis of data traffic requirement and cell change situation, realize the technical scheme of web search；Described by Fig. 5 and Fig. 6 with reference on the basis of data traffic requirement and change in location distance, realize the technical scheme of web search.

Pass through cell change situation or change in location distance, it is essentially all in order to determine the displacement of terminal, to start the search to first network when displacement is larger, so as to both add search success rate, contribute to reduce searching times again, reduce power consumption of terminal.

Meanwhile, based on above-mentioned economize on electricity purpose, if stopping the search to first network, terminal-pair LTE networks may be influenceed（That is first network）Timely access, thus can combine other technologies means, to solve the drawback.

Embodiment one：Timer

In the above-mentioned technical solutions, it is preferable that when the search operation of first network described in the terminal-pair the continuous frequency of failure be more than or equal to preset times when, in addition to：Start timer, and the terminal is after the timer expiry, initiates the search operation to the first network；Wherein, if the search operation to the first network that the terminal is initiated after the timer expiry fails, the timer is restarted.

In the above-mentioned technical solutions, it is preferable that also include：When the search operation to the first network that the terminal is initiated after the timer expiry fails, increase the timing time of the timer according to predetermined manner.

In the technical scheme, by the timing time for increasing timer, frequency of the terminal execution to the search operation of first network can further be reduced, so as to contribute to the power consumption for reducing terminal, be conducive to saving power for terminal,, can be with when quickly being moved particularly with the region on a large scale without the LTE network coverages Significantly reduce searching times.It is of course also possible to use fixed timing length, without being adjusted to timing.

Specifically, Fig. 7 A, which are shown, according to an embodiment of the invention performs the schematic flow sheet of web search based on cell change/change in location distance and timer.

As shown in Figure 7 A, it is according to an embodiment of the invention to be included based on cell change/change in location distance and timer to perform the flow of web search：

Step 702, UE is from LTE off-grids or has not yet registered to LTE networks, and enters LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions.

Step 704, UE can perform the LTE search registration processes based on cell change, referring specifically to Fig. 3 or Fig. 4;Or, UE can perform the LTE search registration processes based on change in location distance, and referring specifically to Fig. 5 or Fig. 6, here is omitted.

Step 706, statistics UE performs continuous frequency of failure N when LTE search is registered.

Wherein, if continuous frequency of failure N is more than or not less than preset times Nl, into step 708, otherwise return to step 704.

Step 708, timer is started, its fixed timing time of ^^ is Tresearch, and specifically, Tresearch time span can be configured as needed.

Step 710, judge whether timer is overtime, if overtime, into step 712, otherwise continue waiting for.

Step 712, control UE performs a LTE search registration.

Because Tresearch time span is longer than the LTE search registration intervals under default situations, thus UE is contributed to economize on electricity；Meanwhile, the LTE search registrations based on timer can be behind the overlay area of UE entrance/return LTE networks, it is ensured that UE accesses LTE in time, it is to avoid period of reservation of number is long.

Step 714, judge that LTE search registers whether success, if success, into step 716, otherwise into step 718.

Step 716, UE exits LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions, and enters normal operating conditions.Step 718, the timing time Tresearch of increase timer numerical value, and return to step 708.By increasing Tresearch numerical value, with reduce LTE search registration number of times, contribute in a big way it is interior be not present the LTE network coverages, or user do not occur relatively large distance it is mobile when, Reduce UE power consumptions.The timing length of certain timer can not also be adjusted, and be arranged to fixed timing length.

Wherein, process is increased for Tresearch numerical value, can be in the following way：

(1) wealthy value Threshold=n χ Tresearch are set, and corresponding to same Threshold, n represents to perform the number of times of LTE search registrations.

(2) after n LTE search registration, Threshold is increased to m times of original (ratio：^ mouthfuls of m=2 or other numerical value）, while still keeping Thresholds χ Tresearch, i.e.,

Tresearch also increases to original m times.

(3) until Threshold increases to default maximum of T hreshold-max, then adjustment Threshold and Tresearch numerical value is stopped.

Certainly, aforesaid way is only used for citing；Skilled in the art realises that be, it is clear that other modes can also be used, such as cause the timing time of timer for n X Tresearch, n is the number of times that LTE searches for registration.

As shown in Fig. 7 B, on the basis of the technical scheme shown in Fig. 7 A, step 718'(correspond to Fig. 7 A shown in step 718) in continuous frequency of failure N numerical value can also be adjusted.Specifically, the numerical value of the continuous frequency of failure N should be reduced（Such as subtract 1), to cause during return to step 706, due to N<N1 and re-execute in step 704 based on cell change/change in location distance LTE search registration process, the utilization so that general's " cell change/change in location distance " and " timer " be combined with each other, searching net frequency, reducing UE power consumption for UE can either be reduced by " timer ", can ensure that UE accesses LTE promptness again by " cell change/change in location distance " again.

It should be noted that：

In Fig. 7 B, " continuous frequency of failure N " is meant that UE performs the number of times of continuous failure when LTE search is registered based on cell change/change in location distance；And when using other counting modes, more technical schemes can also be expanded out.

For example, the LTE realized based on " cell change/change in location distance " and " timer " the frequency of failures searched for when registering can be subjected to unified counting, as long as performing LTE search registrations to operate and failure, " continuous frequency of failure N " will be caused to change, triggering factors without distinguishing LTE search registration operations, help to reduce the complexity of algorithm.Specifically, As " continuous frequency of failure N " while when corresponding to the pass frequency of failure when " cell change/change in location distance " and " timer " searches for registration come the LTE realized, the step 718' in Fig. 7 B can be divided into the following step in Fig. 7 C：

Step 718, A, when the LTE search registration behavior failures initiated based on " timer ", continuous frequency of failure N adds 1.

Step 718, the timing time of timer is increased according to predetermined manner, and the continuous frequency of failure is subtracted 2 (or bigger numerical value）, to ensure N during return to step 706<N1, so as to trigger the LTE search registration processes based on cell change/change in location distance.The timing length of certain timer can not also be adjusted, and be arranged to fixed timing length.

Embodiment two：Area i or renewal

Fig. 8 A, which are shown, according to an embodiment of the invention performs the schematic flow sheet of web search based on cell change/change in location distance and area update.

As shown in Figure 8 A, it is according to an embodiment of the invention to be included based on cell change/change in location distance and area update to perform the flow of web search：

Step 802, UE is from LTE off-grids or has not yet registered to LTE networks, and enters LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions.

Step 804, UE can perform the LTE search registration processes based on cell change, referring specifically to Fig. 3 or Fig. 4;Or, UE can perform the LTE search registration processes based on change in location distance, and referring specifically to Fig. 5 or Fig. 6, here is omitted.

Step 806, statistics UE performs continuous frequency of failure N when LTE search is registered.

Wherein, if continuous frequency of failure N is more than or not less than preset times Nl, into step 808, otherwise return to step 804.

Step 808, judge whether UE has initiated RAU (Routing Area Updating, Route Area i or renewal) or LAU (Location Area Updating, position area i or renewal) request, if, then enter step 810, otherwise continue waiting for.

Step 810, a LTE search registration is performed.

Specifically, due to the initiation that routing region updating is asked or band of position renewal is asked, it is necessarily accompanied with UE change in location, and UE is blunt that the overlay area of LTE networks may be come back to due to the change of the band of position, thus the search operation of LTE networks is not blindly performed accordingly, but First network may be successfully searched with larger, contributes to user's success, rapidly recover to LTE networks, lift Consumer's Experience.

Step 812, judge that LTE search registers whether success, if success, into step 814, otherwise return to step 808.

Step 814, UE exits LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions, and enters normal operating conditions.As shown in Figure 8 B, on the basis of shown in Fig. 8 A, it can also comprise the steps：Step 816, when the LTE search registration behavior failures initiated based on " area update RAU/LAU ", the continuous frequency of failure is subtracted 1 (or bigger numerical value）And return to step 806, to ensure N during return to step 806<N1, so as to trigger the LTE search registration processes based on cell change/change in location distance.

It should be noted that：

" continuous frequency of failure N " in Fig. 8 B corresponds only to the frequency of failure during LTE search registrations realized by " cell change/change in location distance "；And when using other counting modes, more technical schemes can also be expanded out.

For example, the LTE realized based on " cell change/change in location distance " and " area update AU/LAU " the frequency of failures searched for when registering can be subjected to unified counting, as long as performing LTE search registrations to operate and failure, " continuous frequency of failure N " will be caused to change, triggering factors without distinguishing LTE search registration operations, help to reduce the complexity of algorithm.Specifically, as " continuous frequency of failure N " while when corresponding to the pass frequency of failure when " cell change/change in location distance " and " area update RAU/LAU " searches for registration come the LTE realized, the step 816 in Fig. 8 B can be divided into the following step in Fig. 8 C：

Step 816A, when the LTE search registration behavior failures initiated based on " area update RAU/LAU ", continuous frequency of failure N adds 1.

Step 816B, the continuous frequency of failure is subtracted 2 (or bigger numerical value）, to ensure N during return to step 806<N1, so as to trigger the LTE search registration processes based on cell change/change in location distance.

Further, when the variable quantity of above-mentioned one or more auxiliary parameters is more than or equal to default variable quantity accordingly, it can further determine that UE may have occurred the movement of relatively large distance, so as to initiate the registration operation of the search to LTE networks, to lift the success rate of LTE search registrations, it is to avoid the LTE search registrations of blindness operate and cause the waste of UE power consumptions.

Wherein, when UE has data traffic requirement, auxiliary parameter can also be combined with cell change/change in location distance.Specifically, such as the variable quantity of auxiliary parameter can be judged in the case that or change in location constant in cell ID distance is less than pre-determined distance；Or, can also be in the case where the variable quantity of auxiliary parameter be less than default variable quantity accordingly, the size of situation of change or change in location distance to cell ID judges.

Step 906, a LTE search registration is performed.

Step 908, judge that LTE search registers whether success, if success, into step 910, otherwise return to step 902.

Step 910, UE exits LTE BUCKET-BASED SEARCHING BACKGROUNDSearch working conditions, and enters normal operating conditions.Figure 10 shows the schematic block diagram of web search device according to an embodiment of the invention.As shown in Figure 10, web search device 1000 according to an embodiment of the invention, including：Demand detection unit 1002, for, from first network off-grid or when having not yet registered to the first network, detecting in terminal and whether there is data traffic requirement in the terminal；Web search unit 1004, in the case where detecting the presence of the data traffic requirement, performing the search operation to the first network. In the technical scheme, presence situation based on the data traffic requirement in terminal, determine whether to perform the search operation to first network, it is all based on demand so that searching net every time and initiates, both the use demand and applied mental of user had been met, blindness can be avoided to search net again causes the power consumption of terminal to increase, and helps to extend the stand-by time of terminal.

In the above-mentioned technical solutions, it is preferable that also include：Cell change judging unit 1006, for in the case where detecting the presence of the data traffic requirement, if the terminal resides at the second network, judge whether the terminal corresponding serving cell and/or adjacent cell in second network change；Wherein, the web search unit 1004 performs the search operation to the first network in the case where the corresponding serving cell of the terminal and/or adjacent cell change.

In the technical scheme, when residing in the second network, because terminal is necessarily connected to neighbouring cell, so that by knowing that the situation of change of terminal corresponding serving cell and/or adjacent cell in the second network, it just can directly reflect change in location situation of the terminal under the second network, that is the change of serving cell and/or adjacent cell, necessarily due to the change in location of terminal caused by, and terminal Most probably occurs the change in location of relatively large distance.

In the above-mentioned technical solutions, it is preferable that the cell change judging unit 1006 specifically for：Change in the mark of the corresponding serving cell of second network and/or adjacent cell when the terminal, the terminal performs cell selection or cell reselection operation, the terminal in second network in second network from the second network off-grid, the terminal and performs cell handover operations or the terminal in the case where second network performs cell update operation, judges that the corresponding serving cell of the terminal and/or adjacent cell change.

In the above-mentioned technical solutions, it is preferable that the web search unit 1004 is additionally operable to：In the case where the continuous frequency of failure of the search operation of first network described in the terminal-pair is more than or equal to preset times, stop performing the search operation to the first network of the situation of change based on the serving cell and/or adjacent cell.

In the above-mentioned technical solutions, it is preferable that also include：Location information acquiring unit 1008, the real-time position information for obtaining the terminal；Change in location judging unit 1010, for according to the real-time position information, judging whether the change in location distance of the terminal is met more than or equal to default variable quantity；Wherein, the web search unit 1004 in judged result to meet and in the case of detecting the presence of the data traffic requirement, perform the search operation to the first network.

Therefore, when the change in location that terminal is produced is more than or equal to predetermined value, terminal is highly likely to enter/ The overlay area of first network is reentered, then now by performing the search operation to first network, had both added and has searched net success rate, blindness can be avoided to search net again causes the power consumption of terminal to increase, helps to extend the stand-by time of terminal.

In the above-mentioned technical solutions, it is preferable that the location information acquiring unit 1008 specifically for：By the satellite positioning module in the terminal, the real-time position information is obtained；And/or when the terminal resides at the second network, the real-time position information of the terminal is received from network side.

In the above-mentioned technical solutions, it is preferable that the web search unit 1004 is additionally operable to：In the case where the continuous frequency of failure of the search operation of first network described in the terminal-pair is more than or equal to preset times, stop performing the search operation to the first network based on the change in location distance.

In the technical scheme, using the web search mode based on timer, i.e. per after when the timer times out, terminal performs the search operation to first network, if success, accesses first network, otherwise resets timer, to wait after the timer again time out, the search operation to first network is re-executed. Cell is based on because when the continuous frequency of failure is more, terminal stops performing（Serving cell and/or adjacent cell）What is changed searches net operation, thus operated by the above-mentioned web search based on timer, so that while power consumption of terminal is reduced, the promptness scanned for first network can be ensured to a certain extent, it is to avoid the overlay area of user's entrance/return first network can not but be registered for a long time.

In the above-mentioned technical solutions, it is preferable that also include：Web search frequency control unit

1014, for when the search operation to the first network initiated after the timer expiry fails, the continuous frequency of failure is subtracted into default value, to re-execute the situation of change based on the serving cell and/or adjacent cell or the search operation to the first network based on the change in location distance by the web search unit 1004.

In the above-mentioned technical solutions, it is preferable that the timer management unit 1012 is additionally operable to：When the search operation to the first network that the terminal is initiated after the timer expiry fails, the timer is restarted immediately, or increase the timing time of the timer according to predetermined manner and restart the timer.

In the technical scheme, because routing region updating is asked or the band of position updates the initiation of request, be necessarily accompanied with the change in location of terminal, and terminal probably due to the change of the band of position and weigh The new overlay area for returning to first network, thus the search operation of first network is not blindly performed accordingly, but first network may be successfully searched with larger, contribute to user's success, rapidly recover to first network, lift Consumer's Experience.

1014, for when the search operation to the first network for updating request based on routing region updating request or the band of position of initiation fails, the continuous frequency of failure is subtracted into default value, to re-execute the situation of change based on the serving cell and/or adjacent cell or the search operation to the first network based on the change in location distance by the web search unit 1004.

In any of the above-described technical scheme, it is preferable that also include：Combination condition judging unit 1016, for judging whether the terminal meets following combination conditions：In the case where the terminal has data traffic requirement, the changing value of one or more selected parameters of the terminal under second network is more than or equal to default changing value accordingly；Wherein, the web search unit 1004 initiates the search operation to the first network in the case where the terminal meets corresponding conditionses；And the selected parameter includes at least one of or its combination：Signal intensity, the transmission power intensity of the terminal and/or the transmission signal intensity of the corresponding serving cell of the terminal and/or adjacent cell, the corresponding emission delay of the terminal and/or reception delay, the corresponding bit error rate of the terminal and/or Block Error Rate, the corresponding signal to noise ratio of the terminal and/or signal interference ratio.

It is when the change in location of relatively large distance occurs for terminal, the changing value for causing above-mentioned various selected parameters is larger in the technical scheme（Such as larger than or equal to corresponding default changing value）, and terminal is likely to the overlay area of therefore entrance/return first network.So, pass through the determination of the changing value to above-mentioned selected parameter, the change in location situation of terminal can be reflected, this is determined whether that terminal performs the search operation to first network, it can avoid blindly searching net to a certain extent, help to reduce the power consumption of terminal, be conducive to saving power for terminal.
